That way, you can offer incentive for existing customers to upgrade, rather than force the price upon them.
So after 10 years in business you are going to have many different server setups. Sort of unfair on your clients and your employees that have to provide sales/support. An incentive to upgrade for "new technologies" won't sell with your average guy. If it works, he will keep it so don't expect a near 100% upgrade rate
Better to look at trends, price things reasonably so you can eat a price increase. In most cases a reputable provider would be able to lock clients in but if an increase is absolutely needed, plenty of notice is key.
Little off topic: I recall my phone contract provider forced an increased bill / new monthly rate on me citing increased costs for the reason. Fast forward a year or so, a family member of mine works in a partner company meaning I was entitled to a 30% discount (way less than I was originally paying before the increase) :/ - Only increase if you have to as obviously in this case, they could have easily eaten my costs.
